●
INSTALLING A NEW BATTERY — disconnect
negative cable from old battery first and con-
nect to new battery last.
●
CONNECTING A BATTERY CHARGER —

RANGER 305G
OVERSPEED IS HAZARDOUS
The maximum allowable high idle speed for this
machine is 3750 RPM, no load. Do NOT tamper
with governor components or setting or make any
other adjustments to increase the maximum
speed. Severe personal injury and damage to the
machine can result if operated at speeds above
maximum.
CLEANING THE BATTERY
Keep the battery clean by wiping it with a damp cloth
when dirty. If the terminals appear corroded, discon-
nect the battery cables and wash the terminals with an
ammonia solution or a solution of 1/4 pound (0.11kg)
of baking soda and 1 quart (0.1 L) of water. Be sure
the battery vent plugs (if equipped) are tight so that
none of the solution enters the cells.
After cleaning, flush the outside of the battery, the bat-
tery compartment, and surrounding areas with clear
water. Coat the battery terminals lightly with petroleum
jelly or a non-conductive grease to retard corrosion.
Keep the battery clean and dry. Moisture accumula-
tion on the battery can lead to more rapid discharge
and early battery failure.
CHECKING THE ELECTROLYTE LEVEL
If battery cells are low, fill them to the neck of the filler
hole with distilled water and recharge. If one cell is
low, check for leaks.
CHARGING THE BATTERY
When you charge, jump, replace, or otherwise con-
nect battery cables to the battery, be sure the polarity
is correct. Improper polarity can damage the charging
circuit. The RANGER 305G positive (+) battery termi-
nal has a red terminal cover.
If you need to charge the battery with an external
charger, disconnect the negative cable first, then the
positive cable before you attach the charger leads.
After the battery is charged, reconnect the positive
battery cable first and the negative cable last. Failure
to do so can result in damage to the internal charger
components. Follow the instructions of the battery
charger manufacturer for proper charger settings and
charging time.
